DETAILED DESCRIPTION

[00081 [Problems to be Solved by Present Disclosure] [0009] In a case where a general-purpose optical fiber is connected to a circuit board, a connection portion between the optical fiber and the circuit board may be thermally deformed due to heat generated by the circuit board. Suppressing the thermal deformation of the connection portion between the optical fiber and the circuit board ensures the reliability of the optical coupling. For this reason, an optical wiring component has been studied in which an optical connection member formed of a heat-resistant material or structure is provided at one end of the optical fiber connected to the circuit board, and an optical connector configured to be connected to the general-purpose optical fiber is provided at the other end of the optical fiber.

[0010] When the optical wiring component having the above configuration is attached to the base, each of the optical connection member and the optical connector is fixed to the base. Since the length of the optical fiber between the optical connection member and the optical connector needs an extra length to absorb a manufacturing error, the optical fiber fixed to the base by the optical connection member and the optical connector is bent due to the extra length. When a curvature of bending is large, the reliability of the optical coupling between the optical fiber and the circuit is lowered. Therefore, strict precision is required with respect to the arrangement of the optical connection member and the optical connector and the length of the optical fiber so as to reduce degradation of reliability of the optical coupling, and affects productivity as well.

[0011] [Advantageous Effects of Present Disclosure] According to the present disclosure, it is possible to provide an optical wiring component, an optical device, and a method of assembling an optical device in which bending of an optical fiber can be reduced.

[Description of Embodiments of Present Disclosure]

First, embodiments according to the present disclosure will be listed and explained.

[0012] An optical wiring component according to the present disclosure includes an optical fiber, an optical connector, and an optical connection member. The optical fiber has a first end portion and a second end portion. The optical fiber includes one or a plurality of optical fibers. The optical connector is configured to be provided on a base and configured to hold the first end portion. The optical connection member is configured to hold the second end portion. The optical connector includes a terminal member and a changing mechanism. The terminal member is configured to expose the first end portion. The changing mechanism is configured to restrict movement of the optical connector with respect to the base in a first direction and enable movement of the optical connector with respect to the base in a second direction intersecting the first direction.

[0013] In the optical wiring component, the changing mechanism is configured to restrict movement of the optical connector with respect to the base in the first direction and enable movement of the optical connector with respect to the base in the second direction. Therefore, even after the optical connection member and the optical connector are attached to the base, the bending of the optical fiber can be eliminated by the movement of the optical connector in the second direction by the changing mechanism.

[0014] The optical wiring component may further include a positioning member configured to engage with the changing mechanism of the optical connector and position the optical connector with respect to the base. The changing mechanism may be configured to restrict movement of the optical connector with respect to the positioning member in the first direction and enable relative movement of the optical connector with respect to the positioning member in the second direction. In this case, the optical connector can be more easily and reliably positioned with respect to the base by the positioning member, and the bending of the optical fiber can be eliminated by the movement of the optical connector in the second direction.

[0015] The changing mechanism and the positioning member may further include a locking mechanism configured to lock movement of the optical connector with respect to the positioning member. The locking mechanism may be configured to lock movement of the optical connector toward the optical connection member in the second direction. In this case, the optical connector can be fixed at a position where no bending of the optical fiber occurs.

[0016] The locking mechanism may include a plurality of first claw portions and a second claw portion. The plurality of first claw portions may be included in one of the changing mechanism and the positioning member. The second claw portion may be included in the other one of the changing mechanism and the positioning member. The plurality of first claw portions may be arranged in the second direction. The second claw portion may be configured to restrict movement of the optical connector with respect to the positioning member by coming into contact with any of the plurality of first claw portions. In this case, a position at which the optical connector is locked changes according to a positional relationship between the first claw portions and the second claw portion which come in contact with each other. Therefore, the optical connector can be more reliably fixed at a position where no bending of the optical fiber occurs.

[0017] The plurality of first claw portions and the second claw portion may be configured to restrict by coming into contact with each other movement of the optical connector with respect to the positioning member in a direction toward the optical connection member and allow by sliding on each other movement of the optical connector in a direction in which the optical connection member and the optical connector separate from each other. In this case, the movement of the optical connector in a direction in which the bending of the optical fiber is eliminated is allowed, while the movement of the optical connector in a direction in which the bending of the optical fiber occurs is restricted. Therefore, the bending of the optical fiber can be eliminated more easily and reliably.

[0018] The positioning member further may include a curved portion. The curved portion may configured to be displaced in a third direction intersecting the first direction and the second direction.

[00191 The changing mechanism may include a through opening extending through the optical connector in the second direction. The positioning member may be fitted into the through opening and includes a slide surface configured to slide with respect to a surface defining the through opening.

[0020] The optical wiring component may further include a locking member configured to lock movement of the optical connector with respect to the positioning member.

In this case, the optical connector can be fixed at a position where no bending of the optical fiber occurs.

[0021] The locking member may include a pin member. The pin member may be fixed to one of the positioning member and the optical connector. The pin member may be configured to, in a state of being fixed to one of the positioning member and the optical connector, engage with the other one of the positioning member and the optical connector in the second direction and lock movement of the optical connector toward the optical connection member. in this case, the optical connector can be fixed at a position where no bending of the optical fiber occurs by an easier operation.

[0022] The locking member may include a screw. The screw may be screwed into one of the positioning member and the optical connector. The screw may include a tip configured to move with respect to the positioning member and the optical connector in response to turning of the screw. The tip may be configured to engage with the other one of the positioning member and the optical connector and lock movement of the optical connector toward the optical connection member. In this case, the optical connector can be fixed at a position where no bending of the optical fiber occurs by an easy operation using the screw.

[0023] The tip may be configured to move in the second direction in response to turning of the screw. In this case, the fixing position of the optical connector can be adjusted, by turning the screw, with a higher precision to a position where no bending of the optical fiber occurs.

[0024] The tip may be configured to move in the first direction in response to turning of the screw.

[0025] The locking member may include an urging member. The urging member may be fixed to one of the positioning member and the optical connector. The urging member may be configured to urge the optical connector in a direction in which the optical connection member and the optical connector separate from each other in the second direction. In this case, an urging force of the urging member can reduce the occurrence of the bending of the optical fiber and reduce a force applied to a connection portion of the optical connection member due to the bending of the optical fiber.

[0026] The urging member may include a coil spring. The coil spring may have one end fixed to one of the optical connector and the positioning member. The coil spring may have the other end in contact with the other one of the optical connector and the positioning member.

[0027] The urging member may be configured to urge the optical connector with an urging force of 5 N or more.

l00281 The optical connector may be configured to hold the first end portion of the optical fiber such that the first end portion extends in the second direction in the optical connector. In this case, adjusting the position of the optical connector in the second direction can more reliably reduce the bending of the optical fiber.

[0029] The one or plurality of optical fibers may include a first optical fiber and a second optical fiber. Each of the first optical fiber and the second optical fiber may include the first end portion and the second end portion. The one or plurality of optical connectors may include a first optical connector and a second optical connector.

The second optical connector may be configured to hold the first end portion of the second optical fiber. The optical connection member may be configured to hold the second end portion of each of the first optical fiber and the second optical fiber. In this case, the bending can be reduced in each of the optical fibers of different optical connectors connected to one optical connection member.

[0030] The optical fiber may have a length of 20 mm to 100 mm In this case, a thermal influence on the optical connector can be reduced, and a space for arranging the optical wiring component can be reduced. Therefore, the reliability of optical coupling can be improved by a compact configuration.

The optical integrated circuit is optically connected to the optical connection member. The optical integrated circuit and the optical wiring component are disposed at the base.

However, only one optical fiber 11 may be held by optical connector 12C. In. FIG. 8, nine optical fibers 11 are held by optical connector 12C. Optical connector 12C includes a changing mechanism 22C instead of changing mechanism 22.

Tip 44 moves in the Y-axis direction to displace contact portion 42. Accordingly, screw 43 applies a frictional force to changing mechanism 22C through contact portion 42 in response to turning of screw 43. As a result, the movement of optical connector 12C toward optical connection member 14 is locked.

[0073] in a further modification of this modification, changing mechanism 22C may include contact portion 42. In this case, contact portion 42 is displaced in the Y-axis direction in response to an external force and comes into contact with positioning member 13C.

Hereinafter, differences between this modification and the above-described embodiment will be mainly described.

[0075] In this modification, optical connector 12D is configured to hold at least one optical fiber 11. Only one optical fiber 11 is shown in FIG. 9. However, a plurality of optical fibers 11 may be held by optical connector 12D. Optical connector 12D includes a changing mechanism 22D instead of changing mechanism 22C.

Tip 44D is configured to engage with the other one of positioning member 13D and optical connector 12D and lock movement of optical connector 12D toward optical connection member 14.

[0079] In this modification, screw 43D is screwed into positioning member 13D. For example, a screw portion of screw 43D is in contact with positioning member 13D and extends through positioning member 13D to restrict movement of screw 43D. Tip 44D moves in the X-axis direction to come into contact with part P3 of changing mechanism 22D.

As a result, the movement of optical connector 12D toward optical connection member 14 is locked. Terminal member 10 is configured to move together with optical connector 12D in a state in which end portion 9a of optical fiber 9 and end portion lla of optical fiber 11 are optically connected.

[0080] Referring to FIG. 10, an optical wiring component in a modification of the present embodiment will be described.

[0084] Locking member 35E includes an urging member 57. Urging member 57 is fixed to one of positioning member 13E and optical connector 12. Urging member 57 is configured to urge optical connector 12 in a direction in which optical connection member 14 and optical connector 12 separate from each other in the X-axis direction. In this modification, urging member 57 is, for example, a spring. The spring is, for example, a coil spring. One end 57a of the coil spring is, for example, fixed to support surface 55 of positioning member 13E. The other end 57b of the coil spring comes into contact with contact surface 56 of optical connector 12. Terminal member 10 is configured to move together with optical connector 12 in a state in which end portion 9a of optical fiber 9 and end portion lla of optical fiber 11 are optically connected.

[0085] An urging force with which urging member 57 urges optical connector 12 is, for example, greater than a force applied to optical connector 12 by terminal member 10 in the X-axis direction when end portion 9a of optical fiber 9 and end portion lla of optical fiber 11 are connected to each other. Urging member 57 is configured to urge optical connector 12 with an urging force of 5 N or more, for example.

[0086] Referring to FIG. 11, an optical wiring component in a modification of the present embodiment will be described. FIG. 11 is a diagram illustrating the optical wiring component in the modification of the embodiment. This modification is generally similar to or the same as the modification described with reference to FIG. 3. An Optical wiring component 4F in this modification is different from the above-described embodiment in that a plurality of optical fibers 11F, a plurality of optical connectors 12E, and a plurality of positioning members 13F are included. Hereinafter, differences between this modification and the above-described embodiment will be mainly described.

[0087] Optical wiring component 4F includes an optical fiber group 61, 62, 63, and 64. Each of optical fiber groups 61 to 64 includes one or more optical fibers 11F. The one or more optical fibers 11F each include an end portion 1 la and an end portion 1 lb in the same manner as optical fiber 11. In this modification, each of optical fiber groups 61 to 64 includes a plurality of optical fibers 11F extending parallel to one another.

[0088] In the following, differences between optical wiring components 4, 4A, 4B, 4C, 4D, 4E, and 4F in the present embodiment and the modifications, and a comparative example will be described. FIG. 12 shows an optical device 100 as a comparative example. Optical device 100 includes an optical wiring component 101 instead of optical wiring component 4. Optical wiring component 101 includes an optical connector 102 instead of optical connector 12. Optical connector 102 includes no changing mechanism 22. In optical device 100, optical connection member 14 is joined to optical processor 7 of optical integrated circuit 3 at joint surface 14b. Optical connector 102 is directly fixed to base 2. In this case, the length of optical fiber 11 between optical connection member 14 and optical connector 102 needs an extra length to absorb a manufacturing error. However, the extra length causes the optical fiber fixed to the base by the optical connection member and the optical connector to be bent. When the curvature of the bending is large, the reliability of the optical coupling between the optical fiber and the circuit is lowered. In addition, a force generated by the bending of the optical fiber is applied to the connection portion between optical fiber 11 and optical connection member 14, and the connection portion between optical connection member 14 and optical integrated circuit 3. The force generated by the bending becomes larger as the length of optical fiber 11 becomes shorter.

[0089] In contrast, optical wiring component 4 includes changing mechanism 22.

Changing mechanism 22 is configured to restrict the movement of optical connector with respect to the base in the Z-axis direction and the Y-axis direction and enable the movement of optical connector 12 with respect to base 2 in the X-axis direction. Therefore, even after optical connection member 14 and optical connector 12 are attached to base 2, the bending of optical fiber 11 can be eliminated by the movement of optical connector 12 in the X-axis direction by changing mechanism 22. Therefore, according to optical wiling component 4, the bending of the optical fiber can be reduced. Optical wiring components 4A, 4B, 4C, 4D, 4E, and 4F have the same configuration as that of optical wiring component 4, and the bending of optical fiber 11 can be reduced.

[0090] Optical device 1 includes optical wiring component 4, optical integrated circuit 3, and base 2. Optical integrated circuit 3 is optically connected to optical connection member 14. Optical integrated circuit 3 and optical wiring component 4 are disposed at base 2. Therefore, an influence of heat from optical integrated circuit 3 on optical connector 12 can be reduced, and the bending of optical fiber 11 can be reduced. By reducing the bending of optical fiber 11, the occurrence of failure of optical integrated circuit 3 due to the force generated by the bending of optical fiber 11 is reduced, and the reliability of optical coupling is improved as well.

[0091] Optical wiring component 4 includes positioning member 13. Positioning member 13 is configured to engage with changing mechanism 22 of optical connector 12 and position optical connector 12 with respect to base 2. Changing mechanism 22 is configured to restrict the movement of optical connector 12 with respect to positioning member 13 in the Z-axis direction and the Y-axis direction. Changing mechanism 22 is configured to enable the relative movement of optical connector 12 with respect to positioning member 13 in the X-axis direction. In this case, optical connector 12 can be easily and reliably positioned with respect to base 2 by positioning member 13, and the bending of optical fiber 11 can be eliminated by the movement of optical connector 12 in the X-axis direction. Optical wiring components 4A, 4B, 4C, 4D, 4E, and 4F also have the same configuration as optical wiring component 4.

[0092] Changing mechanism 22A and positioning member 13A include locking mechanism 31. Locking mechanism 31 is configured to lock the movement of optical connector 12A with respect to positioning member 13A. Locking mechanism 31 is configured to lock the movement of optical connector 12A toward optical connection member 14 in the X-axis direction. In this case, optical connector 12A can be fixed at a position where no bending of optical fiber 11 occurs.

[0093] Locking mechanism 31 includes a plurality of first claw portions 31a and second claw portion 31h. The plurality of first claw portions 3 1 a are included in one of changing mechanism 22A and positioning member 13A. Second claw portion 31b is included in the other one of changing mechanism 22A and positioning member 13A. The plurality of first claw portions 31a are ananged in the X-axis direction. Second claw portion 31h is configured to restrict the movement of optical connector 12A with respect to positioning member 13A by coming into contact with any of the plurality of first claw portions 31a. In this case, a position at which optical connector 12A is locked changes according to the positional relationship between first claw portions 31a and second claw portion 311) which come into contact with each other. Therefore, optical connector 12A can be more reliably fixed at a position where no bending of optical fiber 11 occurs.

[0094] The plurality of first claw portions 31a and second claw portion 31b may be configured to restrict by coming into contact with each other the movement of optical connector 12A with respect to positioning member 13A in the direction toward optical connection member 14 and allow by sliding on each other the movement of optical connector 12A in the direction in which optical connection member 14 and optical connector 12A separate from each other. In this case, the movement of optical connector 12A in a direction in which the bending of optical fiber 11 is eliminated is allowed, while the movement of optical connector 12A in a direction in which the bending of optical fiber 11 occurs is restricted. Therefore, the bending of optical fiber 11 can be eliminated more easily and reliably.

[0095] Optical wiring component 4B includes locking member 35. Locking member is configured to lock the movement of optical connector 12 with respect to positioning member 13B. Locking member 35 is configured to lock the movement of optical connector 12 toward optical connection member 14 in the X-axis direction. In this case, optical connector 12 can be fixed at a position where no bending of optical fiber 11 occurs. Optical wiring components 4C. 4D, and 4E also have the same configuration as optical wiring component 4B.

[0096] Locking member 35 of optical wiring component 4B includes pin member 36.

Pin member 36 is fixed to one of positioning member 13B and optical connector 12. Pin member 36 is configured to, in a state of being fixed to one of positioning member 13B and optical connector 12, engage with the other one of positioning member 13B and optical connector 12 in the X-axis direction and lock the movement of optical connector 12 toward optical connection member 14. In this case, optical connector 12 can be fixed at a position where no bending of optical fiber 11 occurs by an easier operation.

[0097] Locking member 35C of optical wiring component 4C includes screw 43.

Screw 43 is screwed into one of positioning member 13C and optical connector 12C. Screw 43 includes tip 44. Tip 44 is configured to move with respect to positioning member 13C and optical connector 12C in response to turning of screw 43. Tip 44 is configured to engage with the other one of positioning member 13C and optical connector 12C and lock the movement of optical connector 12C toward optical connection member 14. In this case, optical connector 12C can be fixed at a position where no bending of optical fiber 11 occurs by an easy operation using screw 43. Optical wiring component 4D has the same configuration as optical wiring component 4C.

[00981 Tip 44D of screw 43D of optical wiring component 4D is configured to move in the X-axis direction in response to turning of screw 43D. In this case, the fixing position of optical connector 12D can be adjusted, by turning screw 43D, with a higher precision to a position where no bending of optical fiber 11 occurs.

[0099] Locking member 35E of optical wiring component 4E includes urging member 57. Urging member 57 is screwed into one of positioning member 13E and optical connector 12E. Urging member 57 is configured to urge optical connector 12D in the direction in which optical connection member 14 and optical connector 12D separate from each other in the X-axis direction. In this case, an urging force of urging member 57 can reduce the occurrence of the bending of optical fiber 11 and reduce a force applied to the connection portion of optical connection member 14 due to the bending of optical fiber 11.

[0100] Optical connector 12 of optical wiring component 4 is configured to hold end portion lla so that end portion lla of optical fiber 11 extends in the X-axis direction in optical connector 12. In this case, adjusting the position of optical connector 12 in the X-axis direction can more reliably reduce the bending of optical fiber 11. Optical wiring components 4A, 4B, 4C, 4D, 4E, and 4F also have the same configuration as optical wiring component 4.

[0101] Optical wiring component 4F includes a plurality of optical fibers 11 F and a plurality of optical connectors 12F. The plurality of optical connectors 12F include optical connectors 66, 67, 68, and 69. Optical connector 66 is configured to hold end portions lla of optical fibers 11F included in optical fiber group 61. Optical connector 67 is configured to hold end portions lla of optical fibers 11F included in optical fiber group 62. Optical connection member 14 is configured to hold respective end portions llb of optical fibers 11F included in optical fiber group 61 and optical fiber group 62. In this case, the bending can be reduced in each of optical fibers 11F of different optical connectors 66 and 67 connected to one optical connection member 14.

[0102] Optical fibers 11 and 11F have a length of 20 mm to 100 mm. In this case, thermal influence on optical connectors 12 and 12F can be reduced, and a space for arranging optical wiring components 4 and 4F can be reduced. Therefore, the reliability of optical coupling can be improved by a compact configuration. Optical wiring components 4A, 4B, 4C, 4D, and 4E have the same configuration as optical wiring component 4F.

[01031 The embodiments have been described above. However, the present invention is not necessarily limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

[0104] For example, optical wiring components 4, 4A, 4B, 4C, 4D, 4E, and 4F may include no positioning member. In this case, base 2 may include the positioning member. The positioning member and base 2 may be integrally formed.

[0105] The configurations in optical wiring components 4, 4A, 4B, 4C, 4D, 4E, and 4F may be combined with one another.
